Ph measures how acidic or basic something is. The lower the number the more acidic it is going to be.
Drink A is basic, he can drink that
Drink B is neutral, he can drink that
Drink C is acidic, he should avoid
Drink D is basic, he can drink that
Drink E is acidic, he should avoid
Answer:Strontium-90 and cesium-137 have half-lives of about 30 years (half the radioactivity will decay in 30 years). Plutonium-239 has a half-life of 24,000 years. High-level wastes are hazardous because they produce fatal radiation doses during short periods of direct exposure.

Answer:
D.
Explanation:
I had looked it up on the quiz site
The molecular formula of sucrose is - C₁₂H₂₂O₁₁
molecular mass of sucrose - 342 g/mol
molarity of sucrose solution is 0.758 M
In 1 L solution the number of sucrose moles are - 0.758 mol
Therefore in 1.55 L solution, sucrose moles are - 0.758 mol/L x 1.55 L
= 1.17 mol
The mass of 1.17 mol of sucrose is - 1.17 mol x 342 g/mol = 4.00 x 10² g
